The float switch made of plastic is reliable, maintenance- and wear-free and easy to mount. With voltages up to 5 volts and currents up to 1 mA, up to 1 trillion switching cycles are possible. Water detectors from Elektrotechnik Schabus keep to this limit, here a square-wave alternating voltage of 2.5 Vpp is always switched with high impedance, i.e. with very low current. The normally open contact switches on at a certain level and activates the input of the water detector. By turning the float body around, the reverse contact function is also obtained; with the changeover contact, turning around is not necessary.
Mini float switches are basically used where a water level is signaled, i.e. in tanks, cisterns, wells, in the pump sump and in all other containers where water sensors would be exposed to excessive moisture and thus quickly tend to false alarms, but also accelerated wear. If the 2.5 meter cable is too short for you, please inform us about the required length, we will be happy to manufacture each individual float switch as requested.
LIYY cables are only temporarily waterproof and, according to the manufacturer, flame-retardant, low-adhesion, self-extinguishing and largely resistant to oils, greases, coolants and lubricants.
- Accessories for SCHABUS water detectors SHT 5000 and 5001, 5002
- Material completely made of plastics
- Reed contact with cable soldered and cast in place
- Cable length 2.5 m (special lengths on request)
- Normally closed (NC) / normally open (NO) - Turning the float body corresponds to reversed contact function, not applicable for changeover contact
- Suitable for all liquids with a density of at least 0.7 g/cm³, e.g. water, heating oil, diesel, vegetable oil, lubricating oils, etc.
WARNING
Errors in the electrical connection of magnetic float switches can destroy the reed contacts. This can cause the system to malfunction, resulting in personal injury or material damage!
No direct operation on circuits with inductive loads
No direct operation on circuits with a capacitive load, e.g. PLC, DCS or cable lengths > 50 m
Do not exceed the permissible switching capacity
Connection with inductive load:
With inductive loads, the magnetic float switches must be protected by wiring with an RC element or a free-wheeling diode.
